how to turn off two factor authentication

Hello,

I see you want to disable two-factor authentication. For some background I suggest you read the document: "Two-factor authentication for Apple ID" - Two-factor authentication for Apple ID - Apple Support

From the document:

"If you're already using two-factor authentication with your Apple ID, you can't turn it off."

Two-factor authentication is enabled by default on new Apple IDs and cannot be turned off.

If you have an account where you only very recently activated Two Factor Authentication, note this section of the Apple support article -->

"If you updated to two-factor authentication inadvertently, you can turn it off within two weeks of enrollment. If you do, your account is less secure and you can't use features that require a higher level of security."

If you did indeed recently activate two factor authentication and want to disable it, you should check for an email from Apple. If you don't see one about this, look in your junk mail folder.
